Hi Willy, Thanks for your response. In change http://git.haproxy.org/?p=haproxy-1.8.git;a=commit;h=4f45bb9c461f462290b77bf2511badb7a4453c0a William made shctx more generic. Right now it's calculated:
shctx = (struct shared_context *)mmap(NULL, sizeof(struct shared_context) + extra + (maxblocks * (sizeof(struct shared_block) + blocksize)), before it was: shctx = (struct shared_context *)mmap(NULL, sizeof(struct shared_context)+(size*sizeof(struct shared_block)), Still, William is the best person to ask. :-) 2017-11-28 7:38 GMT+01:00 Willy Tarreau <[email protected]>: > Hi Maciej, > > On Mon, Nov 27, 2017 at 09:15:22AM +0100, Maciej Zdeb wrote: > > Hi, > > > > Thank you for your hard work on HAProxy 1.8 - great job! > > > > I tried to update haproxy from 1.7 on our r&d machine to 1.8 version > > however stumbled upon problem with tune.ssl.cachesize directive. > > > > In 1.7.3 with tune.ssl.cachesize = 10000000: > > > > ps aux | grep haproxy > > USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND > > haproxy 43863 0.1 0.0 2327496 13052 ?
